BOILER-CLEANER.

SPECIFICATION forming part of Letters Patent No. 456,894, dated July 28,1891.

Application led March 17| 1891.

To aZZ whom it may concern:

Be it known that I, THOMAS E. JONES, a citizen of the United States,residing at Bristol, in the county of Sullivan and Stateof Tennessee,have invented a new and useful Boiler-Cleaner, of which the following isa specification.

This invention relates to devices for cleaning boilers, and it hasparticular reference to devices forcleaning vertical or upright boilers.

The invention consists in a revoluble ring mounted in the boiler andhaving scrapers adapted to convey the mud and similar deposits to theblow-out opening, as will be hereinafter fully described, andparticularly pointed out in the claim.

In the drawings hereto annexed, Figure l is a perspective view of myimproved boilercleaning device. Fig. 2 is a horizontal sectional view ofa boiler equipped with the said device. Fig. 3 is a vertical sectionalview of the same.

Like numerals of reference indicate like parts in all the gur'es.

l designates the boiler-casing, which is provided with the blow-off cock2.

3 designates a ring, which is iitied in the lower end of the boiler andwhich is provided at its lower edge with a series ot' Scrapers 4. Theupper edge of the ringS is provided with a circumferential series ofteeth of cogs 5, which are adapted to be engaged by a pinion 6, mountedupon the shaft 7, which is journaled in suitable bearings in theboiler-casing. Suitable packing-boxes are provided to prevent leakagearound the said shaft. They Serial No. 385.406. (No model.)

outer end of the shaft 7 is provided with a handle or crank 8, by meansof which it may be conveniently manipulated to rotate the ring 3.

The operation of this invention will be readily understood from theforegoing description, taken in connection with the drawings heretoannexed. Vhen it is desired to clean the boiler, the blow-off cock isopened and the shaft 7 is then manipulated to rotate the ring 3. TheScrapers upon the latterwill serve t0 loosen the mud and otheraccumulated deposits and to convey the latter toward the blow-outopening, through which they are forced by the escaping steam.

This device, as Will be seen, is exceedingly simple in construction andmay be very readily operated With satisfactory results.

Having thus described my invention, I claim as an improvement inboiler-cleaners- The combination, with a vertical boiler, of a ringsupported upon the bottom of the saine, said ring being provided withteeth or cogs at its upper edge and with downwardly-extending scrapers,a shaft extending transversely through the boiler-casing and havingapinion meshing with the teeth of said ring, and a crank or handle at theouter end of said shaft, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two Witnesses.

THOS.. E. JONES. Witnesses:

C. B. COOK, JOSEPH H. BURROW.
